Abstract
A quick opening envelope which gives full access to its interior upon opening is disclosed. The envelope is formed from a blank constructed from a single sheet of flexible material having a plurality of fold lines defining a front panel, a back panel, two side flaps and a closure flap. The back panel is provided with a V-shaped array of die cut perforations, each of which includes an arc portion and a tangent portion. The V-shaped array of perforations enables neat and easy opening of the envelope.
